Xenon N4,5OO Auger spectrum -: a useful calibration source

In the xenon N(4.)5OOAuger spectrum there are 19 prominent lines ranging in kinetic energy from 8 to 36 eV that provide a convenient set of standards for calibrating electron spectrometers. Combining optical data with recent measurements of this spectrum gives energies for these lines that are absolutely accurate to 11 meV. For most lines the relative accuracy is better than 1 meV-, for a few it is about 3 meV. The spin-orbit splitting of the xenon 4d lines is determined to be 1979.0+/-0.5 meV.
